FOLDING-CASE SYSTEM.

Specification of Letters Patent. Patented Sept, 23 1919.

Application filed J-uly 14, 1917. Serial No. 180,620.

To all whom it may concern Be it known that I,'FERNAND ETIEN E LAVIELLE, a citizen of the French Republic, residing at Bordeaux, in France, have invented a certain new and useful Improve ment in Folding-Case Systems, of which the following is a specification.

This invention relates to cases. for the transport of goods and more particularly tohinges for use in attaching the lid to the body of the case.

In the following description I have illustrated the improved hinges as applied to a folding case of a generally known type.

In the annexed drawing:

Figure 1 is an elevational view of the case erected for use.

Fig. 2 a section on line 2-2 of Fig. 3 showing the right hand end partly turned down.

Fig. 3 an end View of the case showing the lid raised, the two ends erected, the two other sides being kept upright and rigid.

Fig. 4 is an end view illustrating the flexional movement of the two sides for bending them down on the bottom or putting them into rigid position.

Fig. 5 is a partial front elevation of the case collapsed.

I Fig. 6 is a broken horizontal sectional View showing thehinge connecting the lid and the back side.

Fig. 7 is a vertical sectional View of the hinge shown in Fig. 6.

The working mechanism of the constituent parts of the folding case is as follows:

The case comprises a bottom member, a back side member formed of two parts I) a hinged together longitudinally, the lower of these members being hinged as at j to a rail on the edge of the bottom member to fall inward thereover and the upper memher I) being hinged at y to fall outwardly over the lower member 0, a front side mem ber consisting of two parts 5 0 similar to the parts I) 0, two end members d d hinged as at 72 to fall inward upon the bottom member, and a lid a hinged to the back member Z) by means of hinges hereinafter described. At the ends of parts I) 0 b c are angle irons 0 the flanges of which project beyond the inner faces of these parts to form abutments for the end members d (5 when the case is erected. The parts I) b are also provided near each end with slotted plates 9 9 into the slots of which turnbuttons c c pivoted as at f f to the end members (Z (Z can be caused to engage to lock the end members in erected position. Detachable angle irons m m fastened by screws a n to the parts b 6 respectively bridge the ends of the case when erected and hold the parts Z) 6 from falling asunder. The lid a is provided with angle irons Z Z at the ends the projecting flanges of which lie outside the irons m m when the lid is closed on the erected case.

It will be seen that the webs of the angle pieces lie in the thickness of the wood of the back of the case, and that the hinge so formed has no salient portions either on the inside or outside of the case, and therefore is not liable to receive injury itself nor to cause injury from contact with persons or objects.

A tongue 2' is pivoted on the inside of the front of the case and when turned up as shown in Fig. 1, will project through a slot in the top of the case, a wire may then be passed through a hole in the end of the tongue 2' and a lead seal may be fastened upon the wire so as to form a means for assuring that the case shall not be opened without detection. An ordinary lock is also shown at h.

The hinges by which the lid a is connected to the back member I) are shown in detail in Figs. 6 and 7 An angle bracket 0 is fastened to the inside of the lid a and its outstanding web 0 is perforated for passage of a pin 9 which also passes through a hole in the web of another angle piece which is fastened to the inside of the bac: member I) with its web lying in a slot cut in said back member. The wood of the member 6 is cut away to accommodate the head 9 of the pin 9 and the projecting portion of said pin.

In assembling the parts the angle bracket 0 is first secured to the lid of the case by screws, the pin q is then passed from the left through the hole in the web 0 and the other angle piece 2) is threaded on the'proje'cting pin. The angle piece 19 is then fastened in place against the back member of the case. The pin then lies in the slot in the back member, and the head 9 of the pin lies against the wall of the slot so that the pin cannot fall out or be removed except after detachment of the angle piece 7) from the back member of the case.

To collapse the case two ends (l (l are first folded down on the bottom i'then the 7 lower side members 0 0 are slightly pressed and lowered on the bottom, the upper side members I) b folding outwardly as shown, in Fig. .4. The angle iron ebridgin'g'pieces m which connect the two sides Z) 6 follow the movement together with the lid (1.

In order to erect the case the lid a is raised, then the two sides 6 0 b 0 then the ends d ti the twin buttons 0 e are then engagedand the case is ready for use.

'What I claim as my invention and desire to secure by Letters Patent ofthe United States is V In a folding case the combination with the lid member and rear member of ahinge comprising an angle bracket attached to copies of this patent may be; obtained for the face of one of these members and. having a perforated web projecting perpendicularly therefrom, another angle bracket attached, to the faceof the other member and hailing a'perforated web projecting into a slot out in said member, and aheaded pin 'the shankiofwhich passesthrough'the per- 'forations, in said webs, the pin being housed in a recess in the last mentioned member.

In witness whereof'I have signed this specification in the presen'ce oftwo witnesses.. Y V
